Corneal Imaging

Excerpt

Corneal imaging is widely used by ophthalmologists to understand the shape and curvature of the cornea. Corneal topography evaluates the anterior surface of the cornea and displays the information using a color-coded map. On the other hand, corneal tomography takes into account the thickness of the cornea, allowing the posterior surface of the cornea to be elucidated. Their ability to track disease progression, treatment efficacy over time, and screen candidates for particular surgical procedures make them one of ophthalmology’s essential imaging studies. The goal of this article is to understand the basics of corneal topography and tomography, understand its indications, and interpret its findings.
